FAR-INFRARED ABSORPTION DUE TO IMPURITIES IN CsBr CRYSTALS

Determination of mercury by atomic-absorption spectrophotometry.

A flameless atomic-absorption system has been developed for the determination of low concentrations of mercury in gaseous, solid and liquid samples of organic and inorganic materials.

The estimation of magnesium in plasma, muscle and bone, by atomic absorption spectrophotometry.

The use of the EEL 140 atomic absorption spectrophotometer for the determination of magnesium in plasma, skeletal muscle, and bone is described together with an examination of the pattern of chemical interference in each type of sample. The sampling procedure and preparation of each kind of sample for analysis is detailed, and recovery studies on plasma bone and muscle are presented. The mean v...

Estimation of calcium and magnesium in serum and urine by atomic absorption spectrophotometry.

A method has been described for the estimation of calcium and magnesium in serum and urine using atomic absorption spectrophotometry. The precision and accuracy of the techniques have been determined and were found to be acceptable. THE RANGE OF VALUES FOR CALCIUM AND MAGNESIUM IN THE SERA OF NORMAL ADULTS WAS FOUND TO BE: serum calcium (corrected to a specific gravity of 1.026) 8.38-10.08 mg. ...
